VENTILATING WINDOW SHADE AND FIXTURE.

To all whom it may concern Be it known that 1, Louis N. Moss, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Ventilating Window Shades and Fixtures, of which the following is a specification.

in my concurrent application No. 788,559, filed Sept. 8th, 1913, I show and describe means for admitting air through the lower portion of a window sash for purposes of effecting ventilation without raising said sashthe sash itself being of special eonstructio-n. In the present case I seek to attain similar results of privacy with youtilation, when an ordinary lower window sash is raised, by means of an air deflecting and sight-obscuring screen or curtain and supporting side brackets or fixtures of spe cial construct-ion, all as hereinafter described and claimed spccificallydistinctive features being the pivotal support of an automatic roller curtain below the upper inner edge of the window sill and the provision of a plurality of seats on the jambs of the frame for the support of the curtain red at different inclinations and horizontal lev els, whereby diiferent areas of opening may not only be covered so as to obstruct observation theretlirough, but also whereby the incoming air may be controlled and deflected upward at different angles of inclination for the purpose of regulating ventilation. This Il accomplish by means which are simple, cheap, and effective, and which do not interfere with the use or manipulation of the window sash in the ordinary way. Furthermore the shade or screen is readily mounted upon or dismounted from the bracket fixtures which are permanently attached to the jambs of the window frame, thus giving free access to the window for cleaning and similar purposes and rendering the whole window space available in case of emergency. its adaptability to existing windows of ordinary construction renders my device available and effective where more complicated and expensive means of ventilation Etc. would be undesirable or prohibitory.

In the accompanying drawings, Figure 1, is an elevation of the inner side of the lower portion of a window frame and sash showing the practical application of my invention. Fig. 2, is a sectional elevation taken upon plane of line 22 Fig. 1; Fi 3, is

a face elevation of the left hand jamb bracket plate; Fig. at, asimilar view of the right hand jamb bracket plate; Fig. 5, is a sectional detail showing one end of the shade rod seated in one of the jamb brackets.

F represents a window frame of any ordinary or desired construction having the usual sill S the upper inner edge 5, of which is slightly above the seat 3 of the lower bar a, of the lower sash 1%., when closed said sash, of course being counterbalanced and sliding in a vertical way in the usual manner.

Right and left hand bracket plates B, B, are situated respectively on the opposed sides of the frame jambs f, f, being screwed thereto or otherwise permanently secured in position. These bracket plates B, B, are essentially duplicates of each other except that they face in opposite directions; and they are so positioned as to coincide with each other in details horizontally. Each is formed with a socket Z), Z), for the reception of the end pivot of an automatic curtain roller C, of the Hartshorn or other well known type, the socket on the right side of the frame being slotted to admit and hold the flattened pivot or trunnion of the spring spindle in the ordinary manner. Each bracket plate B, is formed with a vertical runway Z), Z), for an end of the curtain rod 0, which rod is preferably round in cross sec tion or has its ends rounded to fit and travel insaid vertical runways 6, Z), as well as in the lateral ways 6 6 in the lower side walls of which are formed the semi-circular seat recesses I), 6*, any of which the ends of the curtain rod 0, fit. Each bracket plate B, is also formed with a comparatively broad flange Z), 7), extending inward toward the center of the window for the purpose of covering and concealing the spaces between the vertical edges of the curtain and the ainbs or rather between said vertical edges of the curtain and the bracket plates themselves. These flanges 5 6 being inclined upward and inward also deflect any air admitted at the vertical edges of the curtain; and they sustain said edges should the curtain be deflected or bent inward by excess of external wind pressure. The fiat flanges Z2 6*, approximate only say one and a half inches in width, and being practically the only parts of the brackets visible from the interior, present no objectionable appearance, especially if the brackets are painted to correspond witl the window frame. Hence their use as permanent fixtures is admissible especially as they t not protrude into or contact the light area; and when the curtain i it and i lowered and wound upon the roller U, i the latter living below the upper edge s, 01

The combination of the janih hr: ckot plates to med with roller trunnion sockets, vertical guide ways, and lateral. guide ways, the lower side ralls of which latter are formed with seating recesses, and a spring roller c irtain inoi'lnted on and between said l)ltl(fl(0li$ and provided with a curtaii'i rod the ends of which protrude beyond the vertical edges of the curtain, engage the said vertical and lateral ways in the jaiahhraclut plates, and are adapted to he sailed in the said recesses foru'ied for their reception in the lateral guide ways as herein set torth.

The combination of the jaiuh h 'ackct plates "formed with roller truunio; sockets, 65 vertical guide ways, and lateral guide ways, the lower side walls of which latter are spring roller curtain mounted on and hetwecu said brackets and provided with a curtain red the ends of which protrude beyond the vertical edges of the curtain, engage the said rcrticzl and lat-er; l ways in the janihhraclwt plates, and are adapt-ed to he Silltfl in the said recesses formed for their reception in the lateral. guide ways, said bracket plates heing' also formed with inturned flanges adapted to overlap and conc al the vertical edges oi" the curtain when raised, as and for LOUIS N. MOSS.
